E-paper name badge

Details

First name Callsigns DOK Occasion, line 1 (in the bar) Occasion, line 2 Photos Orange as Layout Local club line Show local club line Use the DARC logo (I am a DARC member)

You enter your first name yourself. For the callsign the page only checks whether it's in the Bundesnetzagentur (BNetzA, German regulator) list, and suggests a DOK if one is known.

Own picture

Choose picture … No picture yet. You can also drag it onto the preview.

The picture stays in your browser. The panel only knows six colours: in-between shades become dot patterns. Photos with clear areas and strong colours look best.

Write the badge

Badge protocol still being checked. The DMN036EW badge can be written, but the image format has not yet been confirmed on a real badge. Send the test image first: if colours and position are right, your design will fit too. Wrong colours do not harm the badge. Saving as PNG or raw file always works.

Not connected.

Flash firmware

The name badge needs current firmware from the RRG project (Iceman) on the Proxmark. Here it goes on directly over USB, just like with the project's flash tool.

On the device: not checked yet
Will be flashed: –
Variant: –

Which Proxmark? Proxmark3 Easy and others (Generic) Proxmark3 RDV4

An RDV4 has a slot for a SIM-format smartcard and plug-on antennas. Most cheap devices are an Easy (one board with the antennas fixed on it). If current firmware is already running, “Check device” reads this out by itself, as well as the memory size (256 or 512 KB).

Rewrite the bootloader too (only if you know why)

Ready.

Before you start

Don't unplug while it's writing. If it breaks off in the middle of the firmware, just flash again. The page only writes the bootloader if it's too old, and asks first.
The Proxmark restarts twice during this and re-registers on USB. If the page doesn't find it by itself, you choose the port again.
If the page says “hold the button”: keep the small button on the Proxmark pressed until the bootloader step is ticked off.
Linux: ModemManager likes to grab the port itself. Stop it beforehand (sudo systemctl stop ModemManager).
Only with Chrome or Edge on a computer; no other program may have the port open.

Firmware: Proxmark3 from the RRG project, licence GPL-3.0, built by afu.tools from version -. Source code of this version · Licence text

How it works

Design: pick a template and enter first name, callsign and DOK, or load a picture in the Own picture tab and set the crop.
Plug in the Proxmark: via USB to the computer, in Chrome or Edge. It needs current firmware from the RRG project (Iceman). If it has an old one, flash it in the Firmware tab.
Connect: in the Write tab click “Connect Proxmark” and choose the Proxmark's port.
Place the badge: flat and centred on the HF antenna (the large coil at the top), back side down. “Read badge” shows whether it's recognised.
Write: don't move the badge during the transfer. Afterwards the panel refreshes for up to 20 seconds; only then take it off. After that it keeps the image without power.

The DARC logo is a trademark of DARC e.V.
